Astro vs Hugo vs 11ty: Which Static Site Generator Wins

Three Tools, Same Goal, Different Trade-offs

If you have decided to build a marketing site as a static site, the next question is which static site generator to use. The three most popular for marketing sites in 2026 are Astro, Hugo, and 11ty (Eleventy). All three produce fast, SEO-friendly static HTML. The trade-offs are in build speed, developer experience, ecosystem, and how they handle interactive components.

This is not a tier list. The right choice depends on your specific needs, your team's skills, and the kind of site you are building. Here is what to consider.

Astro: Component-First Static Sites

Astro is the newest of the three and the fastest growing. It uses a component model similar to React, Vue, or Svelte, but produces zero JavaScript by default. Components render to static HTML at build time. JavaScript only ships when explicitly opted in via "islands."

Strengths: Modern developer experience for teams familiar with component frameworks. Excellent ecosystem of integrations. Built-in support for content collections (blog posts, programmatic pages). Fast builds. Native support for MDX, JSX, and template syntax.

Weaknesses: Bigger toolchain (Node, Vite, build dependencies) than Hugo or 11ty. Slower builds at very large scale (10K+ pages) compared to Hugo. More moving parts to learn for developers new to component models.

Best for: Marketing sites with 50-5,000 pages where you want a modern component-based developer experience. Sites that need occasional interactive components (search, forms, calculators) without becoming SPAs. Teams that already know React, Vue, or Svelte.

Hugo: The Speed Champion

Hugo is written in Go and famously fast. Build times for sites with 10,000+ pages are measured in seconds, not minutes. The template language (Go templates) is unique and takes adjustment, but the speed advantage compounds over the life of a site that grows.

Strengths: Unmatched build speed at scale. Single binary install (no Node.js, no dependencies). Mature theming ecosystem. Strong programmatic content support. Powerful taxonomies and content organization. Excellent for sites that grow to thousands of pages.

Weaknesses: Go template syntax is unfamiliar to most web developers and frustrating to debug. No native component model. Adding interactive features requires hand-rolled JavaScript or external integration. Steeper learning curve for non-Go developers.

Best for: Programmatic SEO sites with thousands of pages. Documentation sites. Blog-heavy sites where build time matters. Teams comfortable with Go templates or willing to learn them.

11ty (Eleventy): Maximum Flexibility

11ty is the most flexible of the three. It supports multiple template languages (Nunjucks, Liquid, Pug, EJS, Markdown, JavaScript), no opinions about how to structure your site, and minimal build overhead. Built on Node.js with a small dependency footprint.

Strengths: Use the template language you already know. Minimal lock-in. Easy to start small and grow. Native JavaScript-based config. No client-side JavaScript shipped by default. Good for teams that want fine-grained control without imposed architecture.

Weaknesses: Less batteries-included than Astro or Hugo. More configuration decisions to make upfront. Build speed is slower than Hugo at scale (but faster than Next.js or Gatsby).

Best for: Teams that want flexibility without opinions. Sites that need to evolve their structure over time. Developers comfortable with JavaScript and willing to make architectural choices. Smaller marketing sites where developer ergonomics matter more than build speed.

Direct Comparison

Build speed (10K pages): Hugo wins (under 10 seconds typical), Astro second (30-90 seconds), 11ty third (60-180 seconds). For sub-1K page sites, all three are fast enough.

Learning curve: 11ty is easiest if you know JavaScript. Astro is moderate if you know React or Vue. Hugo is hardest because of Go templates.

Component model: Astro has the most modern component model. 11ty supports basic includes and shortcodes. Hugo has partials and shortcodes but no React-style components.

Interactive features: Astro Islands win for adding React/Vue/Svelte components to mostly-static pages. 11ty and Hugo require hand-rolled JavaScript or external libraries.

SEO output: All three produce equivalent static HTML. The SEO winner depends on how you structure your templates, not which generator you choose. Schema markup, meta tags, and semantic HTML are all possible in all three.

What We Use and Why

For the marketing sites we build, we use a hand-rolled Python-based static generator with template inheritance. The reason: we have specific needs around CMS-style programmatic content, schema markup automation, build-time validation, and output optimization that none of the off-the-shelf SSGs handle well enough for our standards. For most teams, that level of customization is overkill.

If you are choosing for a new project: pick Hugo if build speed and scale matter most. Pick Astro if developer experience and component models matter most. Pick 11ty if flexibility and minimal dependencies matter most.

Or skip the choice entirely and have us build the site for you. We deliver 90+ PageSpeed scores, full schema markup, and ownership of every file. Standard sites run $3,000 to $6,000. See services or pricing for details.
